MIAMI (AP) — A U.S. military spokesman says the number of prisoners at Guantanamo Bay labeled as hunger strikers has been raised to 92 based on evaluations by medical personnel at the U.S. base in Cuba.

The new figure is up by eight from a day earlier and represents more than half of the 166 men held there.

Lt. Col. Samuel House says the military arrived at the new figure Wednesday because doctors have been able to evaluate prisoners more closely after moving them to single cells out of a communal area. That move sparked a brief clash between guards and prisoners on April 13.

Lawyers for prisoners have been saying since the strike began in February that the military was undercounting the men refusing to eat in protest of their confinement.
